SPECIFICATION forming part of Letters Patent No. 747,659, `dated :Decemberv 22, 1903. i

' Application filed October 16, 1902. Serial No. 177,289. (No model.)

To all'whom it may concern,.-

Be it known that I, WILHELM STRUBING,

a citizen of the United States, residing at Chicago, in the county of Cookand Stateof Illinois, have invented certain new and use ful Improvements in Temporary Binders, of which the following is a specification. l

My invention relates to temporary binders, and has for its object to provide a binder adapted to receive a number ofy loose leaves upon the ordinary straight telescoping binderposts and to hold the same tightly clamped together, to provide a binder of the character referred to adapted to tightly clampto-4 gether various numbers of leaves as they arev added to or removed from the binder without special adjustment, to provide a binder the binding members of which are positively locked against movement to and from each other at any point of their travel, to provide a binder the binding members of which .can-

not be moved lto andfromeach otherexcept in the manner provided, and in general to provide a simpl'e,'cheap, andxeffective binder of the character referred to.

To the above ends the inventionvconsists in the matters hereinafter described, and more particularly pointed out in the appended claims, and. will be readily understood from the following description, reference being had to the accompanying drawings, in which- Figure l is a front View looking between the cover members. Fig. 2 is a side view with parts broken away. Fig. 3` is a sectional view taken on line 3 3, Fig. 1. Fig. 4 is a fragmentary top view taken from, Fig. l; and Fig. 5 is a fragmetary sectional view taken on line 5 5, Fig. 1. y

Referring to the drawings, 1 and 2 designate two binder members having mounted thereon a pair of straight telescoping binderposts 3 3 adjacent the front edge of said members. 4 tdesignate two other posts mounted adjacent the back edge of said binder member 2 and connected at their tops with a cross-bar 5, secured thereto by the screws 6 6, said posts being somewhat shorter than the telescoping posts. In order to provide a greater bearing or threaded surface for the i screws hereinafter referred to, I provide a block-like member 7, having therein a threaded aperture 8, registering with a similar threaded aperture in the cross-bar '5.

9 designates a screw passing through an aperture in the binder member 1 and having a swiveling engagement therewith at one end and having threaded engagement with the apertures in the cross-bar 5. The head of said screw is adapted to rest flatly upon the upper surface of the binder member 1 and is provided in its top with a socket 10 to receive the end of a key 11, which may be of any desirable construction. Mounted upon said screw immediately underneath the binder" member lis a collar12,vrigidl'y secured to the screw in the present instance by means of a rivet 13. The threads upon said screw 9 are'preferably given more Athan the usualv pitch in order that the binder members l and 2 may be more rapidly moved to and from each other as the screw is turned by means of the key 11. 1

14 and 15 designate two plates secured, respectively, to the binder members l and 2 and overlapping each other to form back andends l of said binder when it is desired to havel the bound ends thus protected. These plates are folded over the binder members at their remote edges and riveted thereto, as shown in Fig. 4. At their ends one is bent around the other (see Fig. 5) and constitutes a guide as the plates overlap and slide upon each other during the movement of the binder members to and from each other in the manner above described. i

16 designates a .label-receiving pocket, which may be mounted upon the back of one of the plates, if desired'.

17 and 18 designate two covers flexibly se cured tothe binder members 1 and 2 in any desirable and well-known manner.`

It is obvious that variations in the details of construction may be made without departing from the spirit of the invention, and Ido not, therefore, limit myself to the details of construction shown and described, except in so far as they are made the subject of specific claims.

I claiml. A temporary binder comprising in combination, a pair of binder members, straight binder-posts mounted upon said binder members and having telescopic engagement With each other, a screw swiveli ugly secured at one end to one of said binder members, a second pair of posts rigidly mounted upon the other binder member, a connecting-bar rigidly secured to said posts and having therein a threaded aperture adapted to receive said screw, means for turning said screw to positively move said binder members to and from each other, and covers iiexibl y secured to said binder members.

2. A temporary binder comprising in combination, a pair of binder members, straight binder-posts secured to said binder members and having telescopic engagement With each other, a screw swivelingly secured to one of said binder members, a pair of posts secured `to the other binder member, a connectingbar secured to the tops of said posts and having therein a threaded aperture to receive said screw, means for rotating said screw, overlapping plate members secured to said binder members to form back and ends thereof, and cover members flexibly united to said binder members, substantially as shown and described.

8. A temporary binder comprising a pair of dat binder members provided with telescoping binder-posts, a screw swiveliuglyaitached at one end to one of said binder members, a pairof posts secured tothe other binder member, a connecting cross-bar rigidly secured to said posts and provided with a thread ed aperture, a block-like member secu red to said connecting cross-bar and provided with a thread ed aperture registering With that of the crossbar, said threaded apertures adapted to receive the free end of said screw, means for rotating said screw, overlapping plate members secured to said binder members to form back and ends thereof, and cover members flexibly united to said binder members, substantially as shown and described.
